| 摘 要： | 物理化学法制备的胶粉粒度比用传统粉碎工艺制备的胶粉粒度要细化得多;延长粉碎时间、增加料筒中介质体积分数、减少装料体积均有利于胶粉细化.试验还显示:用物理化学法制备的精细胶粉粒度低,力学性能也明显优于普通粉碎法. 60～80目胶粉的扯断强度最低,140～200目胶粉的扯断强度最高.

| Abstract: | A new physicochemistry method for producing fine-grade rubber power is introduced. The main factors influencing the effective time in producing fine-grade rubber power are also discussed. The ex- perimental results show that the grade of rubber powder produced with physicochemistry method is much fin- er than that with conventional method. Prolonged grinding time, increased ratio of rubber-power /agent and decreased filling volume can lead to fine-grade rubber powder. The results also show that the mechanical pro- perties of rubber powder by physicochemistry method are superior to that by conventional one, the tensile strength for 60-80 mesh grade rubber powder is the lowest, and for 140-200 mesh grade being the highest. |
